DopplerFX® Accessory Board

This revolutionary accessory for our ShockWave 3 sound system provides enhanced Doppler Shift effects. In conjunction with the ShockWave 3 sound module, the DopplerFX board can make a model airplane sound as though it is going as fast as Mach 0.5 (384 mph or 616km/hr)!

This DopplerFX board is absolutely unique in the RC world.

In summary, in conjunction with the ShockWave 3 sound module, this board produces enhanced Doppler Frequency Shift effects so that when the model is approaching towards, or receding from, the RC operator, it sounds much faster than it is really going.

The model will exhibit a mild Doppler frequency shift due to its own motion, but because the model's speed is much slower than the real airplane, this Doppler shift effect is quite mild. Our ShockWave 3 sound module allows the modeller to set a model speed multiplication factor, up to 7 times, by editing a simple DopplerFXsettings.txt text file on the ShockWave 3's microSD card.

If your model is flying at 50km/hr it can be made to sound as though it is flying at 350km/hr - Wow! A maximum simulated model speed of 385.26mph (616.42km/hr or Mach 0.5) is possible!

The "start point" or "Observer Position" can be set remotely from the RC transmitter so that it can be set to near the judges location, for example, in a scale flying competition.
